I was out testing a boat today, EX17 head, water cooled muffler, Mobil 1 synthetic. Tach showed 4260 rpm, held 4180-4200 for the 5 miles I went up river. Oil temp after that run was 276f, motor was at full throttle the whole time.  Coming back down it stayed around 260-265f. Definitely the high side of the spectrum, would not want to go over 300f and definitely would not recommend conventional oil in these now. Oil should be more than 220f to prevent moisture buildup though, it can be too cool.

Those temps. are similar to my experience which gives me more confidence than I had before after seeing John's results. 
I was out on Vancouver lake today.  The air temp was from about 55 at start and 69 when I pulled out at noon.  I ran for about an hour at 2400-2800 and the high temp was 172 F.  Heading back across the lake I ran at 4440 for about a mile and a half and the high temp was 234.  This with 5W-30 Havoline conventional.  Next change, I am considering switching to Amsoil.

Afer a couple miles the temp was much lower, around 220ish, at 4 miles it broke 260 and seemed to have leveled off at 276 before 5 miles. Again, return trip was with the current and oil temps were cooler. I'm anxious to get my temp gauge installed on my 2011 to see how the results compare now. I have increased inlet air opening and no recoil starter, intercooler for cold air intake, higher compression head, and Amsoil. Next week for sure.  >:D

The test video posted by Tom today was a 2011, if it's the boat I think it is...

Yup, that's your boat man! That temp was after a few miles. Solid boat, very much enjoyed the test ride!  \./8

Thank you Tom, and Thank you Bizler for the TTO adapter! Having engine temp monitoring takes the risk out of guessing. I would like to purchase another one for the next boat!

Thanks everyone for the complement's! It didn't look that 3 weeks ago. With Tom's upgrades, I wouldn't be surprised if the wheels enabled you to drive it to the river!

Haha Thanks guys. I love working on these boats. I started making the covers like that sometime early last year I think, maybe more, can't remember for sure anymore. lol Gives more room and a cleaner look, glad everyone likes it.  ;D

George, I adjusted the governor arm so it keeps the weights from extending at all. The gear is fine like that and has no effect on rpm freewheeling in there.  \./8

I made another trip today from the south shore of Vancouver Lake down Lake River to the Ridgefield boat ramp and back. It took 4 hours.  I didn't turn the engine off at all.  Most of the trip I ran at 3600 rpm.  The high oil temp at this speed was 204.  I ran at full speed, 4440, for about 30 minutes.  The Max temp. was 245.  At idle speed, while passing by the two floating home colonies, 2100 rpm, temp cooled to 167.  So there are a few more data points for those who might be interested.

If you are contemplating getting a Trail Tech gage, I have a couple more adapters.  IM or EM me and I will mail one to you, no charge, first come first served while they last or until someone decides to make them for sale.
Hey Bill,   I have a few questions about the oil temperature sensor.    If you remember my post where I setup my temperature sensor on the spark plug which was probably not a accurate temperature reading on the motor. :-[     Then you setup your sensor in one of the oil fill caps which showed more accurate readings. \./8    My question is,  how much oil do you think is still in the reservoir at mid range to full rpm's because most of the oil is being splashed about the interior of the motor? ???     Do you think the temperature reading is more representative of the motor cases rather than the oil?    Then when at idle the oil comes into contact with the sensor, actually cooling down the sensor.   Just a thought. ::)   On my next run I'm going to set up my sensor on one of the bolts on the top of the motor away from the muffler.

John,   By the way I've got the splash shield cut out and ready to install. \./8
